Harvard, Quera, MIT and NIST / University of Maryland inaugurate a new era of quantum computer science by performing complex quantum algorithms on 48 logical qubits corrected by errors.
The main developer of quantum computers using neutral atoms, Quera Computing, announced significant research progress and presented the results in the scientific journal Nature. In experiences by Harvard University in close collaboration with Quera Computing, MIT and NIST / UMD, researchers have successfully implemented large -scale algorithms on a quantum computer with 48 logical qubits and hundreds of interconnected logical operations. This important breakthrough in quantum computers has marked the start of the development of truly scalable quantum computers and tolerant to errors capable of solving practically insoluble problems of a classic nature.
Deleting errors is a key challenge to reach an effective quantum calculation, requiring the use of quantum error correction for large -scale treatment. However, redundancy in the implementation of “logical” qubits corrected by mistake, where information is coded through many physical qubits to ensure reliability, lays important challenges for scientists and researchers in the creation of large -scale quantum calculations.
Previous demonstrations of error correction have shown one, two or three logical qubits. This new work demonstrates the quantum error correction in 48 logical qubits, improving computer stability and reliability while solving the error problem.
By taking advantage of the logical control and using zoned architecture in programmable networks of neutral atoms, the researchers combined doors with two high fidelity qubits, random interconnection and fully programmable unique qubit rotations and a mid-chain reading. By running this logical processor with different types of coding, they have demonstrated the improvement of logical doors to two qubit by increasing the distance from the surface code, preparing color code qubits with loss -free loyalty, a faultless generation of GHz logical status and teleportation of the interconnected recording and the operation of 40 quict of color code. Using 3D code blocks, they implemented complex sampling circuits in calculation with 48 logical qubits connected to hypercube connectivity with 228 logic doors with two qubit and 48 logic CCZ doors.
The researchers found that this logical coding considerably improves the detection performance of algorithmic errors, outperforming the reliability of physical qubits in the cross reference and quantum rapid entry. These results mark the beginning of the era of early quantum computers and open the way to large -scale logical processors.
The realization of the 48 logical tolerant matters to breakdowns is an important step in the field of quantum computers. This breakthrough accelerates not only the adoption of practical quantum applications, but also opens up new possibilities for solving problems which were previously considered to be intractable using traditional computer methods. This changes the situation and considerably increases the commercial relevance of quantum computer science. Researchers suggest that companies and businesses in various sectors should pay attention to this study, because the race for quantum advantage has now taken a significant momentum.
If subsequent experiences are also successful, we may soon have an evolutionary and tolerant quantum calculation in breakdowns which could solve some of the most difficult problems in the world.
The future of quantum technology is already there!
